Change the country where Google account is managed

Many years ago, I had signed up for a Google Account when I lived in the UK. I have since moved to Germany, and changed my address, country for Google Play and contact telephone number all to Germany (and currently there is no payment information on file, but previously it was a German credit card linked to a German address)

However, it seems that Google still considers me to be a UK customer, as I received an email informing me that the data centre responsible for my account will be moved to the United States. The pertinent excerpts from Google’s email are:

The changes will take effect on March 31, 2020, and they won’t impact the way you use Google services. And, because the United Kingdom (UK) is leaving the European Union (EU), Google LLC will now be the service provider and the data controller responsible for your information and for complying with applicable privacy laws for UK consumer users.

Because the UK is leaving the EU, we’ve updated our Terms so that a United States based company, Google LLC, is now your service provider instead of Google Ireland Limited. Google LLC will also become the data controller responsible for your information and complying with applicable privacy laws.

However, as a customer residing in Germany, I believe my data should continue to be hosted in Ireland and be governed by European laws. I do not want processing of my data to be subject to US or UK laws.
Short of deleting my account, is there any option to change the ‘true’ country account. Account deletion is highly undesirable, as (1) it would means dropping my current GoogleID, which I like for its simplicity, (2) require transferring over a large number of documents in Google Drive, several of them under active collaborative editing, and some other reasons.

I spent some time trawling through the Google Support pages, but all country changes anyone ever seems to talk about there is for Google Play, which I have already changed many years ago to the correct country.
